[0057] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0058] Figures 1 to 6 The diagram shown is a structural schematic of an embodiment of the electrically retractable grandstand seat with dual power supplies according to this utility model. The electrically retractable grandstand seat with dual power supplies includes a storage support frame 1.

[0059] The seat 2 and the seat back 3 are connected at one end by a folding assembly 4, which is used to rotate the seat back 3.

[0060] A partition 5 is connected to the side of the seat back panel 3 away from the seat seat 2.

[0061] The telescopic mechanism is installed in the inner cavity of the storage support frame 1. The telescopic mechanism includes a height adjustment component 6 and a power component 7. The power component 7 is connected to the height adjustment component 6. The height adjustment component 6 is connected to the bottom of the seat plate 2. The power component 7 is used to provide driving force for the rotation of the height adjustment component 6. The height adjustment component 6 is used to adjust the height of the seat plate 2.

[0062] Power supply unit 8 is installed at the bottom of the inner cavity of the storage support frame 1, and is electrically connected to the folding component 4 and the power component 7 respectively.

[0063] In this technical solution, the folding component 4 can be used to fold the seat back panel 3 onto the surface of the seat seat 2. At this time, the cover plate 5 can be moved. The cover plate 5 completely covers the seat seat 2 and the storage support frame 1 and other structures, so that the grandstand seats occupy little space when not in use, and can be treated to prevent dust, rain and sun, which helps to extend the service life of the grandstand seats.

[0064] The area of ​​the shield 5 is larger than the area of ​​the top surface of the storage support frame 1.

[0065] In this technical solution, the shield 5 can be used to protect the grandstand seats when they are not in use.

[0066] The folding assembly 4 includes a bidirectional drive source 41, which is installed in the inner cavity of one side of the seat plate 2. Both output ends of the bidirectional drive source 41 are connected to a drive shaft 42.

[0067] The two drive shafts 42 are connected to a lower gear 43 at the end away from the bidirectional drive source 41. The side of the lower gear 43 meshes with the side of the upper gear 44. The upper gear 44 is connected to the end face of the rotating shaft 45. The surface of the rotating shaft 45 is fixedly and through-connected to one end of the seat back panel 3.

[0068] In this technical solution, the folding assembly 4 is used to fold the seat plate 2 and the seat back plate 3, thereby reducing the space occupied by the grandstand seats.

[0069] Both ends of the rotating shaft 45 are connected to upper gears 44;

[0070] The top of the seat plate 2 is connected to two symmetrically distributed support side plates 46, and the surface of the upper gear 44 is rotatably connected to the support side plates 46.

[0071] In this technical solution, the rotating shaft 45 can be supported by the supporting side plate 46.

[0072] In use, the bidirectional drive source 41 can drive the transmission shaft 42 to rotate, thereby driving the lower gear 43 to rotate, which in turn drives the upper gear 44 to rotate. At this time, the seat back panel 3 can be rotated, thereby folding the seat back panel 3 to the top of the seat seat 2, reducing the space occupied by the grandstand seats.

[0073] When the seat back panel 3 rotates, it can drive the cover plate 5 to rotate. When the seat seat 2 and seat back panel 3 are folded, the cover plate 5 can cover the seat seat 2 and the storage support frame 1 and other structures. Thus, the cover plate 5 can protect the seat seat 2 from rain, sun and dust, thereby extending the service life of the grandstand seats and reducing the cost of using the grandstand seats.

[0074] The height adjustment component 6 includes a bidirectional threaded shaft 61, the two ends of which are rotatably connected to the inner wall of the storage support frame 1.

[0075] The surface of the bidirectional threaded shaft 61 is threadedly connected to two symmetrically distributed movable plates 62;

[0076] Two height adjustment columns 63 are provided above the movable plate 62. Both ends of the height adjustment column 63 are rotatably connected to a rotating frame 64. The lower rotating frame 64 is connected to the top of the movable plate 62, and the upper rotating frame 64 is connected to the bottom of the seat plate 2.

[0077] In this technical solution, the height of the seat plate 2 can be adjusted using the height adjustment component 6, thereby enabling the grandstand seats to extend and retract.

[0078] The inner wall of the storage support frame 1 is connected to multiple anti-deviation rails 65, and the surface of the anti-deviation rails 65 is slidably connected to the movable plate 62.

[0079] In this technical solution, the movement trajectory of the moving plate 62 can be limited by the anti-deviation track 65.

[0080] Depending on the user's height, the power component 7 can drive the bidirectional threaded shaft 61 to rotate, which can drive the moving plates 62 on both sides to move towards or away from each other. With the cooperation of the rotating frame 64, the height adjustment column 63 can be rotated, thereby driving the seat plate 2 to move up and down. At this time, the height of the grandstand seat can be adjusted to accommodate users of different heights.

[0081] The power assembly 7 includes a unidirectional drive source 71, which is installed in the inner cavity of the housing support frame 1.

[0082] The output end of the unidirectional drive source 71 is connected to a drive gear 72, and the side of the drive gear 72 is meshed with a driven gear 73, which is fixed to the surface of the bidirectional threaded shaft 61.

[0083] In this technical solution, the power component 7 can provide driving force for the rotation of the bidirectional threaded shaft 61.

[0084] In use, the unidirectional drive source 71 drives the drive gear 72 to rotate, which in turn drives the driven gear 73 to rotate, which in turn drives the bidirectional threaded shaft 61 to rotate.

[0085] The telescopic mechanism also includes a locking component 9, which includes a movable toothed plate 91 and a locking toothed plate 92.

[0086] The locking toothed plate 92 is disposed below the movable plate 62, and the bottom of the movable plate 62 is connected to the movable toothed plate 91. When the movable toothed plate 91 and the locking toothed plate 92 are in contact, they engage.

[0087] In this technical solution, the operation of the height adjustment component 6 can be locked using the locking component 9, thereby improving the stability of the seat plate 2.

[0088] The bottom of the locking toothed plate 92 is connected to a plurality of telescopic devices 93, which are connected to the bottom of the inner cavity of the storage support frame 1.

[0089] In this technical solution, the position of the locking tooth plate 92 can be adjusted using the telescopic device 93.

[0090] When the grandstand seats are adjusted, the telescopic device 93 drives the locking tooth plate 92 to move upward, so that the locking tooth plate 92 and the moving tooth plate 91 are in close contact. The locking tooth plate 92 locks the position of the moving tooth plate 91, thereby locking the height of the seat plate 2 and increasing the stability of the seat plate 2 support.

[0091] The power supply group 8 consists of two power supplies, each with an independent power supply circuit, and each power supply is electrically connected to the bidirectional drive source 41, the unidirectional drive source 71, and the telescopic device 93.

[0092] In this technical solution, both power supplies of the power supply group 8 can supply power to the bidirectional drive source 41, the drive gear 72, and the telescopic device 93.

[0093] The bidirectional drive source 41 is a bidirectional motor or other device capable of outputting bidirectional rotational kinetic energy.

[0094] The unidirectional drive source 71 is a motor or other device that can output rotational kinetic energy.

[0095] The telescopic device 93 is an electric push rod or other component with autonomous telescopic function.
